. HAIR CLIPPER Filed Feb. 7, 1958 Patented Mar. 19, 1940 UNITED STATES PATENT OFFICE HAIR CLIPPER Riley W. Marshall, Kansas City, Mo. Application February '7, 1938, Serial No. 189,137

1 Claim. (01. 30-196) vide an outer cutter with novel means by which the clipper may be easily and quickly operated while evenly cutting the hair.

A further object of my invention is the provision of an outer cutter which has a convex streamlined outer surface from which project the peripheries of two transverse rollers of different diameters and at the rear of the cutter teeth.

A further object of my invention is the provision of a cutter which is simple, cheap to make, strong, durable, which can be embodied as a unit in a clipper when the latter is made, or which may be applied with a small amount of change thereto to outer cutters already completed and assembled in clippers.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates a preferred embodiment of my invention,

Fig. 1 is a side view of a hair clipper in which the outer cutter comprises the usual form of outer cutter which has been altered and my improvement added thereto.

Fig. 2 is a front view of the cutter shown in Fig. 1,

Fig. 3 is a front view of the attachable roller holder and the rollers mounted therein, detached from the toothed member of the cutter.

Fig. 4 is an outside front view of the toothed member of the cutter shown in Fig. 1, with the roller holder removed.

Fig. 5 is an enlarged section on the line 5-5 of Fig. 3.

Figs. 6 and 7 are respectively front and end views of a modification on which the toothed base member and the roller holding member are in one piece.

Similar characters of reference designate similar parts in the different views.

I designates the body of an ordinary electric hair clipper, having at its front end the usual reciprocating inner cutter 2.

Referring to Figs. 1 to 5, 3 designates a usual outer toothed cutter which has been modified by cutting out of its front side, at the rear of its toothed front end portion 4, a notch 5 in which is fitted a roller holding member 6 having a convex front side 1 and provided in its front end with a recessed portion 8, in which are rotatably fitted two rotary parallel transverse rollers 9 and ID, the front roller 9 being disposed closely adjacent to the rear end of the toothed portion 4 of the member 3, which will be termed the base member.

The base member 3 in its notched portion 4 is I provided therethrough with two holes II which respectively register with two holes 12. Two screws l3 extend through the holes II and I2 and into the body I for holding the member 6 and the member 3 together and to the body l. 10 The holes l2 are located in the rear end portion of the member 6.

The rear roller ill is preferably of greater diameter than the front roller 9, and the peripheries of both rollers project a short distance only from 1 the convex surface 1, whereby they serve as a rolling support against the skin, which makes the operation of the clipper easy, when it is used to clip thehair around the neck and temples, even when the skin is wet with perspiration. The convex streamlined surface 1 of the roller holding member 6 enables the outer cutter to. readily follow the curvatures of the neck and lower portion of the head, while retaining the cutters at an even distance from the skin, so as to evenly cut the hair.

In the form of my invention shown in Figs. 1 to 5, the roller carrying holder is made separate from the base member 3, to enable my invention being applied to outer cutter members already made, and possibly being in use.

In the form of my invention shown in Figs. 6 and 7, the roller carrying member is made in one piece with the toothed member, thus forming an integral member, designated by M. The 35 front end of the cutter member M has the usual toothed portion 4, and the front side of the member I4 is convex, similar to the convex surface 1 of the roller holding member 6, such convex surface |5 of the member 14 preferably starting at or closely adjacent to the toothed portion 4, and being provided with a recessed portion l6 having mounted therein rotary rollers 9 and H) corresponding to the rollers 9 and it of the other form of my invention, and similarly located with respect to the toothed portion 4.

The member M is fastened to the body I by two screws l3, in a manner similar to the fastening of the cutter members 3 and 6.

The mode of operation of the form shown in Figs. 6 and '7 corresponds to the mode of operation of the form shown in Figs. 1 to 5.

Preferably, for lightness, the roller holder 6 may be made of aluminum, and the bodies of the rollers 9 and 10, can be made of soft rubber.

By having two rollers 9 and it) closely adjacent to each other and to the front toothed portion, a rolling support is provided, freeing the front portion from the load, and effecting two functions, that of reducing the resistance offered by moist skin to a minimum, and that of enabling sharp turns to be made in following the curvatures of the neck and head.

By having the roller H] of relatively large diameter with its periphery at a distance greater than the roller 9 from the inner side of the cutter member 3, the resistance is reduced more than were the roller ID of the same diameter as the roller 9, due to a large roller offering less resistance in traveling than a smaller one.

By recessing the front side of the cutter memher 3 and mounting the roller holding member in the recessed portion, it is practicable to use a roller it! of larger diameter than were the holder mounted upon the cutter member 3 unrecessed.

Other modifications of my invention, within the scope of the appended claim, may be made without departing from the spirit of my invention.

What I claim is:

In a hair clipper of the kind described, in combination, a cutter member having a front toothed portion and a recessed portion at the rear of said toothed portion and at the outer side of said cutter member, a roller holding member mounted in said recessed portion, and two transverse rollers one in front of the other rctatably mounted on said roller holding member, the front roller being disposed closely adjacent to said toothed portion and to said rear roller, the said rear roller having a diameter greater than the diameter of said front roller and having the outer part of its periphery at a greater distance from the inner side of said cutter member, than the outer part of the periphery of said front roller.
